rod to neutral position. The arrangement .may be such, however, that the arm 33 will lock the shifter rods when the transmission is in gear at either speed for the forward propulsion of the vehicle, or in neutral.

The head 31 is provided with a stop armV 34 adapted to be projected as shown by Figures 1 and2 into the path of .the clutch l sleeve 18 and prevent movementl of said sleeve to the left from the position shown by Figure 1, thus locking the clutch in engagement, and preventing it from being thrown oft. rThe arm 34'preferably includes an `anti-friction roll 345L which is the portion of the arm contacting with the clutch sleeve. When the plunger 30 is raised the arms 33 and 34 are inoperative, as shown by Figure 3.

The usual cover plate 36 covering the opening 37 provided in lthe transmissioncase for access to theinterior of the case, is provided, in accordance with my invention, with an arm 38 having a finger 39 (Figure 3). Thehead 31 is provided with a stop formed as a slotted ear 40,the slot 41 of which is adapted to engage `the finger 39,

as shown by-Figure 1, when the-plungery and head are depressed, so that the cover plate is locked and cannot be removedA or displaced to permit the insertion into the transmission case of a Itampering device forv unlocking or releasing the clutch member `15. The depression of the plunger to lock the elements above described may also cause the locking of the starter switch 42 in its inoperative position as neXt described.

A loc-king device or stop 43 (Figure 2) is `movable in the path of the switch 42 and is connected by a rod 44 with an arm 45 of a bell crank lever which is fulcrumed at 46 to the standard 21. The other arm 47 of said lever projects ythrough a slot 48 in the guide 28 and is slotted to engage a stud 49 on the plunger 30. When the plunger is ldepressed the stop 43 is projected under the locked. As shown by Figures 3 and 4 the plunger is providedvwith a push and pull rod .51 which projects above kthe guide 28 and has a head or handle 52 enabling the driver to depress the plunger by pushing the rod, and to raise the plunger by pulling 'the rod.

l When the plunger is depressed it is locked,

in' its depressed position. lThe stud 54 isI adapted to be turned by a key 58 removably inserted in aslot' or keyhole formed in the stud.L Vihen the stud is thus turned the bolt l5,3 is moved out of engagement with the tongue 56', so thata spring 59 connecting the plunger withv the stud 54, is permittedA to raise the plunger, until the bolt 53 springs into the notch 57 in Figure 3.

1n the modification shown by Figures 5v and 6 a rod 6() is adapted to be pulled upward to depress the plunger and'pushed downward to raise thel plunger, the rod be ing engaged with a lever 61 pivoted at 62 to ears on the stud 54,- and fulcrumed at 63 on the tongue 56. It will now be seen that when the plunger is depressed and locked it cannot be released and raised until the key 54 is inserted and turned.

lt will also be seen that I haveV provided locking means for locking the transmission gears and locking means for the locking of the movable clutch'member when it is in engagement or performing its usual function. These locking means cflectually prevent successful extended movement of the vehicle by power externally applied.

ln some cases it may be desirable to elongate and curve the guide 28 as indicated in Figure 1 for the convenience of the driver inmanipulating the key 58 .and the handle 52, the elongation and curvature being such thatrthe upper end of the guideY28 is between the gear shift lever 2O and the emergency lever (not shown). rllhe plunger and the rod will, of course, be correspondingly curved. The rod may be made in sections connected by a hinge or joint.

lt will be observed that the locking arm 33 engages the shifter rods or shifter fork rods V19 at a point forward of the gear yshift the tongue, as shown by klever 20, said rods being lengthened -or eX- tended forward to cooperate with the lock-v ing arm. This is a feature in transmission locks which is new with me.

l claim: i ,1. In a motor vehicle, in combination, transmission and clutch mechanism includ-.

ing a shifter rod and al movable clutch member; and locking means comprising a guide fixed below the iioor of the vehicle andpro-l jecting upward above the floor of the vehicle, so that its upper end is out of reach ofthe drivers foot, aplunger manually movable loo having an opening, and an opening'cover provided with a locking member; and locks` ing means comprising a guide `fixed to vand projecting upward from the case lthrough and above the floor, so that its upper end is out of reach of the drivers foot, a plunger manually movable in saidguide, stop devices carried by the` plunger within Vthe case,4

adapted to simultaneously enga'getheshifterv rod, the movable lclutch member, and the locking member of the cover toV confine theV same when the plunger is depressed, and4 means for locking the plunger tothe guide, when said devices are operative, thecover of the case opening, when locked, preventing" access to the stop devices. Y 3. In a motor vehicle,y in combination, transmission and clutch mechanism including a shifter rod and a movable clutch meins ber having a sleeve, said mechanism being enclosed in a case having an opening and an opening cover provided witha locking mein- .,ber, and locking means comprising aguide fixed to'and projecting upward from the,

case through and above the fioor, a plunger Vmanually movable in said guide' and pro- Y vided with a head having a stop adapted to'A engage theforward end of the shifterrod, a

stop adapted to engage the rear end ofthe clutch sleeve, and. a stop adapted to engage .the locking member of thecover, said stops i being rendered simultaneously operative Awhen the plunger is depressed, and means for locking the plunger to the guide when -the stops are-operative. V- I 4. In a motor vehicle, in combination, f' transmission and clutch mechanism includ-- ing a shifter rod and amovable clutch member having a sleeve; and locking means comprising a guide fixed below vthe floor ofthe vehicle and projectingnpward abovefthel floor of the vehicle, so that its upper end is out of reach of the drivers foot, a plunger manually movable in said guide, stop ydevices carriedv by theplunger adapted to si-.'

multaneousfly engage the shifter'rod and the sleeve of the movable clutch member, to conine the same when the plunger is depressed, and plunger-locking means including astud adapted to be rotated by: a kevin a fixed bearing inthe guide, and a spring-pressed bolt carried by and movable inthe stud and vadapted Atobe engaged withV the plunger to lock "the same in' a depressed position, lby a rotation of the stud.
